A scooter telescopic frame structure includes a rear frame body and a set of frames disposed on the rear frame body; a set portion disposed between the front and rear frame bodies, the assembly portion is mounted on the frame Between the front frame body and the rear frame body, the front frame body and the rear frame body are selectively reciprocally movable relative to each other to achieve the purpose of changing the total length of the frame; a limiting member, the limiting member includes There is a front plate body and a rear plate body. The front side of the front plate body is pivoted on the front edge of the front frame body, and the rear edge of the rear plate body is pivotally disposed on the front edge of the rear frame body and the rear side of the front plate body The side system is pivotally connected to the front side of the rear plate body; the pivotal axis of the front plate body and the front frame body and the pivot axis of the rear plate body and the rear frame body are provided with a connecting axis, the connecting axis The horizontal height is greater than the horizontal height of the pivot axis of the front plate body and the rear plate body, so that the distance between the pivot axis between the front plate body and the rear plate body and the assembly portion is smaller than the connecting axis and the The distance between the groups.一種代步車伸縮車架結構,包括一後架體以及一組設於該後架體上之前架體;一設置於該前、後架體間之組接部,該組接部係裝設於該前架體與後架體之間,令該前架體與該後架體可選擇性地相對往復移動,而達改變車架總長度之目的;一限位構件,該限位構件係包含有一前板體以及一後板體,該前板體之前側邊係樞設於前架體之前緣、該後板體之後緣係樞設於該後架體之前緣且該前板體之後側邊係樞接於該後板體之前側邊;該前板體與該前架體之樞接軸線以及該後板體與該後架體之樞接軸線間係設置有一連軸線,該連軸線之水平高度係大於該前板體與後板體之樞接軸線之水平高度,令該前板體與後板體間之樞接軸線與該組接部間的距離,小於該連軸線與該組接部間的距離。
